You would need to make a proper enclosure for them. Since this is for
use outside an fully enclosed "infinite baffle" box would be best (i.e.
no reflex ports etc). Perhaps a WBP ply box that you could clad with
deck boards to make it blend in better. Seal all the joins with
silicone, and stuff it with some wadding.


I was going to say that, but then realised that as they are fully
sealed, any enclosure you put them in isn't going to affect the air
pressure on the rear of the cones, so sealing the enclosure and adding
wadding ain't gonna make a blind bit of difference ;-(
